Story of two German spies attempting to hise out in Cairo, and British plans to foil them.

Fairly accurate retelling of a real German spy operation, which was foiled when the two spies selected turned out to be more interested in spending money on liquor and prostitutes instead of spying. The last ten minutes turn into high melodrama, but a servicable war story otherwise.

Peter Van Eyck's briefly seen explorer character is based on the same real person protrayed by Ralph Fiennes in The English Patient.
